CLOSURE FOR BOTTLES.

Application filed January 8, 1923. Serial No. 611,342.

My invention relates to improvements in closuresfor bottles, and it is intended to I several views, in which Figure 1 is a front elevation of the upper portion of the bottle, provided with a closure constructed according to my invention Figure 2 is a side elevationof the device shown in Fig. 1, as seen from the left of said g g InFigs. 1 and 2, the bottle is shown in the sealed position;

Figure 3 shows the device. after the cap has been ruptured.

Figure 4 shows a section along the broken line 4 4 of Figure 1, and looking in the direction of the arrows, the parts being shown on a larger scale than in Figure 1, and

Figure 5 shows a modification, parts being broken away.

Referring first to Figures 1 to 4:, A represents the neckof the bottle, which neck may be of any suitable design and is provided near its top with the usual annular groove a. B represents a cup-shaped cap made of strong ductile metal, the lower edges of which cap are forced in the said annular groove a. This cap is provided at one side with a notch 79 and adjacent to which notch are parallel weakening grooves ,b', which are rolled or otherwise formed into said cap, and tend to weaken'the same in the vertical plane, so that a strip 6 may be torn out, as will be hereinafter described.

C represents a strip of flexible metal of suflicient strength to tear the metal cap when pulled upwards with sufficient force, and to tear a tongue or strip 6 between the parallel weakening lines Z), as shown in Fig. 3. One or both ends of this strip 0 projects down below the cap B when the parts are in the assembled relation, and to one of these projecting ends a tag D- is preferably attached. This tag may serve both as a thumb lug and a plane surface for hearing advertising or identifying matter. This tag may be connected to the strip C in any convenient way.

The cap C is mounted over the upper end of the bottle and covers the cork E, which may be of any convenient or suitable type. As shown in Fig. 4, the cork is an integral mass E .having shoulders e edging the top of the bottle, or the cork may be of any suit able preferred type, as this is not a part of, my invention, which relates purely to the cap and means for assembling and removing same when desired.

By having the metal cap provided with the weakening grooves b as described, a comparatively stiff and strong metal may be used, and this may be conveniently ruptured when desired, but in certain cases, such stiif and strong metal cap may not be required and may be replaced by a metal cap of softer metal, which may be easily ruptured, such as is shown in Fig. 5, where B represents a metal cap of soft metal, such as lead, tin, or the like, the lower edge of which is forced into the groove on as before described, and C represents the ribbon or tape pass ing between the cap and the stopper E, and to which the tag D may be secured in any convenient way.

WVit-h the construction shown in Fig. 5,

a sufficient pull upwards on the tape or ribbon C will rupture the-cap and will permit its ready removal without the necessity for providing weakening grooves as described in connection with the other figures.

While the hereinbefore described device is intended specially for a closure for bottles, it will be evidently suitable for use with jugs, demijohns, or other containers for liquid whether made of glass, earthenware, metal, or'other suitable material.

It will be obvious that various changes in the construction and combination and arrangement of parts might be made, which could be usedwithout departing from the spirit of my invention, and I do not mean to limit the invention to such details, except as particularly pointed out in the claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

In a closure for bottles, the combination with a bottle provided with an annular groove in the neekthereof near the top of the bottle, of a cup shaped metal cap clos- Q emme ing the top of the bottle and having its lower projecting through said notch, said weakenedges pressed into the groove, one edge of mg grooves extending in parallel relation to 10 said cap being provided with a notch and. the lateral edges of said flat strip, whereby parallel weakening grooves leading upwardto tear a ribbon of metal from the cap bely from the side walls of the notch, and a tween the grooves when the strip is pulled separate strong flat strip extending across upwardly.

the top of the bottle inside said cap and having one end protruding below said cap and SAL G. MILLER.
